Broadcast Program Scene Report System and Method, Mobile Terminal Device, and Computer Program

Abstract

A mobile terminal 20 receives a scene notification message via a communication network 10 . The scene notification message at least includes scene identification information for identifying a scene corresponding to a part of a broadcast program, broadcast identification information on the time-difference broadcast of the scene, and URL information for accessing a server in which scene data is stored. Based on the scene notification message, the mobile terminal 20 receives a time-difference broadcast if it is a time at which the scene can be viewed by the time-difference broadcast and, if not, accesses a server 48 , in which the data of the scene is stored, to acquire the data of the scene.
